(The following post includes new updates as of 2/2/2018)
IGEL has acted quickly in response to the recently disclosed Meltdown and Spectre vulnerabilities with fixes released today.
As background, Meltdown and Spectre affect computer processors, with Meltdown (CVE-2017-5754, critical) affecting Intel CPUs only, and Spectre (CVE-2017-5753 and CVE-2017-5715, high) affecting processors from Intel, AMD and ARM. These vulnerabilities may allow software to read information from other programs and the operating system that they shouldn’t be able to access, for example passwords.
Today IGEL releases fixed firmware images and updates. IGEL strongly recommends updating your devices to these. Note: Any information provided does not release the customer from their obligation to test system modifications in advance. New firmware must always be tested in advance.

NEW: As of 2/2/2018 the new release contains the Kernel Page Table Isolation (KPTI) patch for the Linux Kernel which fixes Meltdown (CVE-2017-5754). Intel has withdrawn its processor microcode updates intended to mitigate the Spectre variant 2 vulnerability (CVE-2017-5715) because of undesirable side-effects that have been seen on some systems. IGEL has removed these microcode updates from IGEL OS as recommended by Intel. Apart from that, the IGEL OS kernel has received fixes for a dozen other vulnerabilities, details can be found in the release notes.
Mozilla Firefox has been updated to protect users from a side-channel attack that uses Spectre and from a number of other vulnerabilities. The default SMB version in IGEL OS 10 has been changed from 1.0 to 2.0 for security reasons. However, administrators can still set another version if desired. We recommend updating your devices.
The following fixed versions are available for download:
- IGEL OS 10.03.570 (LX) for updating IGEL UD-LX devices
- IGEL OS 10.03.570 (OS) for updating UD Pocket und 3rd-party devices converted with UDC3
Information about IGEL Linux 5:
Currently, there is no fix for IGEL Linux 5, as the Linux Kernel developers have not integrated measures against Meltdown into the 32-bit version of the kernel. This affects IGEL Linux 5 and all other 32-bit Linux systems on the market. Currently there is no Meltdown fix in the 32-bit mainline Linux Kernel, but it may become available later. In the meantime, protection from the vulnerabilities can be provided via microcode updates from the processor vendors. IGEL will integrate these as soon as they become available.
Further Windows Information:
Windows devices will also need microcode updates for a complete fix of Spectre. IGEL will deliver these as soon as they become available.
It is our commitment to deliver the most resilient and secure endpoint security and optimization solutions possible. We will continue to pursue every avenue to deliver on this commitment so that our customers can be assured every protection for their IGEL-enabled end user computing devices.
